A43b 13/38 U.S. Cl. 36-432 Claims ABSTRACT OF THE DISCLOSUREl A precast or molded insole forshoes adapted for use with several different heights of high heelscomprising a paddle-shaped forepart, a shank depression extendinglongitudinally from in the heel area forwardly to about midway of theinsole for the reception of a metal shank, and the like, after lasting,the heel portion rearwardly of the shank depression increasing inthickness, the insole being suitably contoured for elimination of theuse of a ller and to provide streamlined appearance.

BACKGROUND OF THE INVENTION (1) Field of the invention The presentinvention relates generally to the shoe art, and more particularly to anovel precast or molded insole affording use thereof with severalheights of high heels.

(2) Description of the prior art The shoe industry has long needed aninsole which can be used with more than one height of high heel withoutcausing the heel to gap at the back. The applicants novel insole fulllsthe long need.

SUMMARY OF THE INVENTION In brief, the present novel insole includes alongitudinally extending recess from in the heel area forwardlyapproximately to the halfway mark of the insole, the heel arearearwardly of the recess being of greatest thickness at the back anddecreasing forwardly to the rear end of the recess, an integral llerportion on the bottom side of the insole being provided to eliminatefiller material.

Objects of the invention are to provide a novel insole which is adaptedto be used with several heights of high heels without effecting gapingat the back, which is formed to receive a metal shank, and the like,after the heel has `been attached, which is streamlined to present aneat appearance, which obviates the use of iiller, and which otherwisefullls the objects and advantages sought thereo for.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a top plan view of an insoleincorporating the teachings of the present invention;

FIG. 2 is a bottom plan view thereof; and

FIGS. 3, 4, 5, 6, 7 and 8 are vertical, cross-sectional views taken onsubstantially the lines 3 3, 4 4, 5 5, 6 6, 7 7 and 8 8-, respectively.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawing moreparticularly by reference numerals, 10 indicates generally an insoleincorporating the principles of the present invention. The insole 10 isformed with a paddle-type forepart 12, being of substantially uniformthickness except for a depending central area 14 adapted to obviate thenecessity of filler in the shoe. An elongated recess 16 is providedwhich extends forwardly from within the heel portion 18 to a pointsubstantially midway of the insole 10, the recess 16 being 'within thearea of the thickened filler portion. The heel portion from the rearpoint 20 of the recess 16 to the rear point 22 of the heel portion 18gradually increases in thickness, as is clear from FIGS. 3 and 8. Thisincrease in thickness permits several heights of high heels to beapplied to the heel portion 18 of the insole 10 without gaping at therear, that is, in proper treading relation. A steel shank, or the like,can be placed in the recess 1-6 before the heel has been applied to theheel portion 18 of the insole, which permits forming of the shank beforeinsertion into the recess, so that it may have the proper curvature forthe particular height of heel applied. It is not practical to bendshanks molded into an insole.

It is manifest that there has been provided an insole which fullls theobjects and advantages sought therefor.

It is to be understood that the foregoing description and theaccompanying drawing have been given by way of illustration and example.It is also to be understood that changes in form of the elements,rearrangement of parts, and substitution of equivalent elements, whichwill be obvious to those skilled in the art, are contemplated as withinthe scope of the present invention which is limited only by the claimswhich follow.

What is claimed is:

1. A cast molded insole formed to permit operative use thereof with highheels of several heights comprising a forepart, a central portionthickened on the bottom interiorly of the sides adapted to extend intothe space above an outsole inwardly of the edges of the turned underportion of an upper, an elongated recess in the thickened bottom centralportion adapted to receive a formed selected shank without therequirement of increasing the over-all effective thickness of the insoleand without weakening the insole, and a heel portion graduallythickening rearwardly from about the rear of the recess for selectivelyoperatively receiving high heels of several heights without gaping, saidelongated shank recess extending into the heel area.

a 2. The insole of claim 1 in which the forepart is of paddleconfiguration.
